VANCOUVER, Aug. 1, 2019 /CNW/ - Pan American Silver Corp. (NASDAQ: PAAS) (TSX: PAAS) today announced results from the exploration drilling completed over the past three months at its 100% owned La Colorada skarn discovery in Mexico.

"We are very pleased with the outstanding recent drill results at La Colorada, which further define the skarn mineralization," said Christopher Emerson, Pan American's Vice President Business Development and Geology. "In particular, drillholes U-51 and U-46 indicate the high concentration of base metal and silver sulphides over large widths. The drill holes now cover a horizontal area of about 600 metres by 300 metres, delineating skarn and manto zones that are still open laterally and at depth."

Drill highlights include:
•U-51-19: 114.0 m at 109 g/t Ag, 0.38% Cu, 1.66% Pb and 3.80% Zn
•including 58.2 m at 158 g/t Ag, 0.59% Cu, 2.57% Pb and 5.08% Zn
•U-46-19: 126.0 m at 55 g/t Ag, 0.22% Cu, 3.79% Pb and 6.56% Zn
•and 32.9 m at 74 g/t Ag, 0.44% Cu, 5.38% Pb and 10.29% Zn
•U-42-19: 214.2 m at 40 g/t Ag, 0.17% Cu, 1.24% Pb and 2.78% Zn
•including 38.3 m at 75 g/t Ag, 0.33% Cu, 3.35% Pb and 3.54% Zn
•U-37-19: 45.8 m at 28 g/t Ag, 0.11% Cu, 1.93% Pb and 3.94% Zn
•and 18.1 m at 36 g/t Ag, 0.08% Cu, 3.16% Pb and 3.71% Zn
•U-35-19: 82.6 m at 41 g/t Ag, 0.3% Cu, 0.92% Pb and 3.96% Zn
•U-29-19: 18.8 m at 67 g/t Ag, 0.23% Cu, 1.48% Pb and 4.53% Zn
•U-22-19*: 104.7 m at 42 g/t Ag, 0.05% Cu, 0.84% Pb and 3.88% Zn
•and 15.1 m at 64 g/t Ag, 0.28% Cu, 2.01% Pb and 5.85% Zn
* Continuation of partial results from hole U-22-19 disclosed in news release dated May 8, 2019.

During the second quarter of 2019, drilling activity on the skarn target increased with four drill rigs operating underground and three drill rigs on surface. More than 11,300 metres of infill and step-out drilling was completed, bringing the total metres drilled to date to over 31,000 metres. The drill results define a polymetallic mineralized skarn system starting 300 metres below the current production level of the La Colorada mine. Each drill hole has intersected multiple mineralized horizons and veins with varying widths. Additionally, drill holes U-37, 42, 46 and 53 all intersected mineralized hydrothermal breccia, a previously unknown mineralizing event.

Over the remainder of 2019, Pan American plans to complete a 50,000 metre drill program and review the results of a 12 kilometre magnetotellurics geophysics survey undertaken at the La Colorada mine to better define the skarn footprint limits and the location of higher concentrations of sulphides. Pan American plans to provide an initial resource estimate of the skarn discovery in late 2019.

Pan American first announced the La Colorada exploration discovery on October 23, 2018, and provided additional drill results on February 21, 2019 and May 8, 2019.

A summary of the recent drill results is provided in the following table(1)(2). The previously released drill results are not included in this table.

General Notes with Respect to Technical Information

Grades are shown as contained metal before mill recoveries are applied. Samples from drill hole U-22-19 and U-23-19 given in this news release were prepared and assayed using fire assay with gravimetric finish for gold by Bureau Veritas in Hermosillo, Mexico and by acid digestion with ICP finish for silver, lead, zinc, and copper in their Vancouver, Canada laboratory. Samples from U-26-19 to U-53-19 and partial samples from U-22-19 were prepared and assayed by SGS in Durango, Mexico using fire assay with gravimetric finish for gold, and by acid digestion with ICP finish for silver, lead, zinc, and copper. Pan American implements a quality assurance and quality control ("QAQC") program including the submission of certified standards, blanks, and duplicate samples to the laboratories. The results of the QAQC samples submitted to SGS and Bureau Veritas demonstrate acceptable accuracy and precision. The Qualified Person is of the opinion that the sample preparation, analytical, and security procedures followed for the samples are sufficient and reliable for the purpose of any future mineral resource and mineral reserve estimates.
